According to media reports, U.S. warships launched over 50 Tomahawk cruise missiles at a Syrian military airfield in the center province of Homs at dawn Friday. A monitor group said at least four Syrian soldiers have been killed.

U.S. President Donald Trump said earlier that he had ordered the strikes and called the operations in the nation’s “vital interest.”

“Russia will first of all demand an urgent meeting of the UN Security Council,” Ozerov was quoted as saying by the RIA Novosti news agency.

Ozerov said that the U.S. missile strike will likely worsen the already clouded relations between Moscow and Washington and hurt bilateral military cooperation as the United States failed to communicate properly on the matter.
